Spider Control for Texas Homes
Updated June 14, 2026
Here's the reassuring truth most Texans don't hear: the overwhelming majority of spiders in and around your home are harmless and are actually doing you a favor by eating other insects. The big, fast wolf spider on the garage floor and the long-legged cellar "daddy long-legs" look alarming but can't hurt you. Only two spiders in Texas are a genuine medical concern — the black widow and the brown recluse — and both are shy and hide in undisturbed places. The key insight for control: spiders follow their food. A home with lots of spiders almost always has lots of other insects, so the real fix targets the prey, not just the webs.
The harmless majority
Wolf spiders (large, fast, ground-hunting, no web), jumping spiders (small, curious, often on sunny walls), cellar spiders ("daddy long-legs"), and common house spiders make up nearly everything you'll see. None are a danger to people or pets. They're nuisance-and-creep-factor pests, not health threats — and they're quietly controlling other bugs.
The two that matter — black widow
Shiny jet-black with the red hourglass underneath, the black widow likes dark, dry, undisturbed spots: garages, sheds, woodpiles, under outdoor furniture, in meter and irrigation boxes, and around the foundation. It's not aggressive and bites only when pressed against skin (reaching into a glove, box, or woodpile), but its venom is neurotoxic and a bite warrants medical attention, especially for kids.
The two that matter — brown recluse
Tan with a darker violin-shaped marking behind the head, the recluse is exactly what its name says — it hides in quiet, undisturbed places indoors and out: closets, storage boxes, attics, behind furniture, in seldom-worn shoes and clothing. Bites are uncommon and usually happen when one gets trapped against skin, but the venom can cause a slow-healing wound, so a suspected recluse bite is worth a doctor's look.
Why you have spiders (the prey connection)
Spiders set up where the food is — porch lights that draw moths, insect-rich landscaping, cluttered garages, and damp areas all support the bugs spiders eat. That's why "just knocking down webs" never lasts: as long as the insect supply is there, new spiders move in. Reduce the insects and the harborage, and the spider population falls with it.
DIY vs. a pro — honestly
You can do a lot yourself: de-clutter garages and closets, knock down webs and egg sacs regularly, seal gaps, switch porch lights to bug-resistant bulbs, and use glue boards along walls to monitor. Where a pro helps is a confirmed brown-recluse or black-widow presence (their harborage is hard to reach and the stakes are higher) and breaking the cycle by treating the insect prey base, which most homeowners overlook.
How Root handles spiders
We treat the underlying insect prey and the harborage and entry points spiders use, knock down webs and egg sacs, and pay special attention to the garages, sheds, storage, and foundation voids where widows and recluses hide. Because our techs know these neighborhoods, they know where the two dangerous species tend to harbor locally. Same-day service is available when capacity allows — useful if you've found a widow or recluse near living space.
